Dr. Hongjie Zhang is a Research Scientist at the Swift Current Research and Development Centre, Agriculture and Agri-Food Canada (AAFC). His research focuses on enhancing the environmental sustainability and resilience of agroecosystems through improved soil health, soil carbon (C) cycling, and agronomy. His research goal is to increase soil C sequestration and reduce greenhouse gas (GHG) emissions in integrated cropping–livestock systems across the Canadian Prairies, thereby enhancing agroecosystem resilience and productivity. To achieve this, he applies stable isotope tracers (¹³C and ¹⁵N) along with advanced spectroscopic techniques—including solid-state ¹³C NMR (CPMAS NMR) and synchrotron-based XANES—to trace the fate of C and nitrogen (N) in plant–soil systems and characterize soil organic carbon (SOC) chemistry. Overall, his research examines how soil management and agricultural practices influence the turnover of C and N inputs, the formation of stable soil organic matter, and the buildup of SOC in cropping and livestock systems to support long-term sustainability and productivity.
